DEVICE FOR TEMPERING WHEAT.

specification of Letters Patent. Patented Aug. 19,1913.

Application iled August 28, 1912. Serial No. 717,574.

T0 all whom t may concern Be it known that I, FRANK F. BOND, a citizenof the rUnited States, residing at Noblesville, in the county of'Hamilton and4 State of Indiana, have invented new and usefulImprovements in Devices for Tempering Wheat, of which the following is aspecification.

This invention relates to devices for tempering wheat and other grainsby spraying the same with water preparatory to milling the same.

The invention has for its object to produce a spraying nozzle of simpleand improved construction whereby the desired result may be effected.

A further object of the invention is to produce a simple and improvedspraying nozzle having means whereby the operation may be regulated.

YWith these and other ends in view which will readily appear as thenature of the invention is better understood, fhe same consists in theimproved construction and novel arrangement and combination of part-swhich will be hereinafter Jfully described and particularly pointed outin the claims.

In the accompanying drawing has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may be resorted to when desired.

In the drawing,-Figure 1 is a side view of a nozzle constructed inaccordance with the invention. Fig. 2 is a longitudinal sectional viewof the same. Fig. 3 is a transverse sectional view taken on the line 3 3in Fig. 2.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The improved nozzle comprises in it-s construction an outer cylindricaltube l and an inner tube 2, which latter is located concentricallywithin the outer tube, extending about half way therethrough, said innertube being provided at one end with an elbowI 3 which is connected withthe side wall of the outer tube, as shown at 4, so as to produce aninlet aperture 5 communicating with the inner tube. The outer tube isprovided at vreception of a sleeve 9 having an interior annular flange10 the opening through which flares outwardly, as shown. That portion ofvthe tube B which projects beyond the front end of the tube A isprovided with an annular recess 11 of V-shaped cross section,.and at thebottom of said recess are formed apertures 12 through which water mayescape, the eXtreme front end of the tube 2 being obstructed by a plug13. A portion of the tube 2 in front of the V-shaped recess 11 isexteriorly threaded for the reception of a cap or sleeve 14, the innerend of which has an annular V-shaped flange 15 projecting in thedirection of the flange 12 of the cap 9, but spaced from the latter soas to present an annular aperture 16. A similare annular aperture 17exists between the inner edge of the ange 10 and the annularly recessedpo-rtion of the tube 2, said annular aperture 17 being formed betweenthe inclined rear portion of the wall of the il-shaped recess 7 and theinner edge of the flange 10. It will be obvious that by properadjustment of the cap 9 upon the threaded end of the pipe, the area ofthe aperture 17 may be increased or diminished at will, therebyregulating the escape of compressed air. The area of the aperture 16 maybe regulated by adjustment of' the sleeve or cap 14, as will be readilyunderstood.

In the operation of this device, it is intended that the water shall besupplied under little or no pressure, the quantity of water beingregulated by simple well known means, such as an ordinary valve 18 onthe supply pipe 8. The quantity of the water supply may thus beeffectively regulated. The water escaping in numerous small jets throughthe aperturps 12 will be subjected to the pressure of the annular air etissuing through the aperture 17, and the velocity oft which may beregulated by proper adjustment of the cap 9. The spray thus formed 'willissue through the annular aperture lfm and the velocity thereoll inay beregulated by proper adjustment ot the cap or sleeve lll.

Having thus described the invention, what is clainielfl as new, is

l. l'n a device oit the class described, an external tube. an inner tubehaving` an elbow connected to the Wall of the outer tube, said innertube extending beyond the front end of the orter tune, and theprojecting portion of said inner tube being` provided with an annularrecess lli-shaped in cross section and with an annular series ofperforations at the bottoni oi said recess, a plug obstructing the frontend oit the inner tube, a sleeve threaded on the front end ot the outertube and having a. forwardly beveled flange extending in the directionof the recessed portion of the inner tube and spaced therefrom toproduce an annular' discharge aperture7 the area of which may beregulated by adjust-nient of the cajnand a sleeve threaded upon theinner tube and cooperating with the tlanged cap to produce an annulardischarge aperture, the area of which inay be varied by adjustment ofthe sleeve,

2. A. nozzle comprising` inner and outer tubular ducts, a sleeveadjustable upon the enter duct and cooperating` with the inner duct tocontrol the quantity of fluid issuing between said outer duct and theinner duct, and a sleeve adjustable on the inner duct and cooperating`with the sleeve on the out/er duct to vary the area of the annularopening between said sleeves.

In testiinony whereof I affix iny signature in presence of tivoWitnesses.
